What Is FIRE?
FIRE stands for Financial Independence, Retire Early. The idea is simple: save and invest aggressively until your investments can pay for your lifestyle, so working becomes a choice rather than a necessity.
Your FIRE number is the size of that investment corpus. Once you reach it, you can withdraw a small percentage every year to cover your expenses, while the rest keeps growing.
How to Use This FIRE Calculator
- Current monthly expenses: what you spend today on your lifestyle.
- Current age and retire at age: your timeline.
- Inflation: how fast your expenses will rise (6% is a common assumption in India).
- Safe withdrawal rate: the share of your corpus you will withdraw each year.
- Current investments and expected return: what you already have and how you expect it to grow.
You'll see your monthly expenses at retirement, your FIRE number, and the monthly SIP needed to get there. The year-by-year table above shows your progress.
How the FIRE Number Is Calculated
- Annual expenses at retirement = today's monthly expenses × 12, grown by inflation until you retire
- Safe withdrawal rate = the % of the corpus you withdraw each year (e.g. 3.5%)
Example: age 30, spends ₹50,000 a month, wants to retire at 45
- At 6% inflation, ₹50,000 today becomes about ₹1,19,828 a month in 15 years.
- At a 3.5% withdrawal rate, the FIRE number is about ₹4.11 crore.
- With ₹5 lakh already invested and 12% returns, the SIP needed is about ₹75,999 a month.
What Is a Safe Withdrawal Rate?
The well-known 4% rule comes from US research. It suggests you can withdraw 4% of your corpus in the first year and adjust for inflation after that, with a low chance of running out of money over about 30 years.
Many Indian planners prefer a lower rate of 3–3.5%, because inflation in India is usually higher and early retirees need their money to last 40 years or more. A lower withdrawal rate means a bigger FIRE number, but a safer retirement.
Why Inflation Matters So Much
Your expenses at retirement will be much higher than today. Here's ₹50,000 a month of expenses grown at 6% inflation:
| Years from now | Same lifestyle will cost |
|---|---|
| 10 years | ₹89,542 a month |
| 15 years | ₹1,19,828 a month |
| 20 years | ₹1,60,357 a month |
| 25 years | ₹2,14,594 a month |
This is why a FIRE number based on today's expenses is too small. The calculator inflates your expenses automatically.
FIRE Number Table (In Today's Money)
A quick reference for how big your corpus needs to be at today's prices:
| Monthly expenses | FIRE number at 4% | FIRE number at 3.5% |
|---|---|---|
| ₹30,000 | ₹90 L | ₹1.03 Cr |
| ₹50,000 | ₹1.50 Cr | ₹1.71 Cr |
| ₹75,000 | ₹2.25 Cr | ₹2.57 Cr |
| ₹1,00,000 | ₹3.00 Cr | ₹3.43 Cr |
Before inflation. Your real target will be higher depending on how many years away retirement is.
Types of FIRE
Retire on a minimal budget. A smaller corpus, but less room for extras.
Retire with a comfortable or luxurious lifestyle. It needs a much bigger corpus.
Leave full-time work but keep a part-time income to cover some expenses.
Save enough early that growth alone reaches your target. You only need to cover today's expenses.
Steps to Reach FIRE
- Track your expenses for a few months to know your real number.
- Raise your savings rate. FIRE seekers often save 40–60% of their income.
- Invest for growth, mainly through equity mutual funds and index funds via SIPs.
- Increase your income with skills, promotions or side income.
- Avoid lifestyle inflation. Put raises into investments, not spending.
- Review every year and update the calculator with real numbers.
Things to Plan for Before You Retire Early
- Health insurance: without an employer policy, you need your own adequate cover.
- Emergency fund: keep 1–2 years of expenses in safe, liquid instruments.
- Big future goals: children's education, marriage or a house need separate funds on top of your FIRE number.
- Market crashes: a fall right after you retire hurts most, so many early retirees keep a few years of expenses in debt funds.
Frequently Asked Questions
What is a FIRE number?
Your FIRE number is the investment corpus you need to cover your yearly expenses from withdrawals for the rest of your life. It is usually calculated as annual expenses divided by a safe withdrawal rate.
Is the 4% rule safe in India?
The 4% rule comes from US data. Because inflation in India is usually higher and early retirements can last 40+ years, many planners prefer a more conservative 3–3.5% withdrawal rate.
How much do I need to retire early in India?
It depends on your expenses, how far away retirement is, inflation and your withdrawal rate. For example, ₹50,000 of monthly expenses today needs about ₹1.71 crore at a 3.5% withdrawal rate in today's money, and more once inflation is included.
What return should I assume?
For a long-term equity-heavy portfolio, 10–12% a year is a common assumption. Using a slightly lower return gives you a safety margin.
Does the FIRE number include my house or EPF?
Only include assets that can generate income or be withdrawn for living expenses. Your own home does not count. EPF, PPF and NPS can count toward your corpus, but check when you can withdraw from them.
What if I cannot invest the SIP amount shown?
Try a later retirement age, lower expenses, or a step-up SIP that grows with your income. Small changes in timeline make a big difference.
